What to Focus On

  • A quadratic polynomial has degree two.
  • A quadratic polynomial equated to zero gives a quadratic equation.
  • Quadratic equations in this chapter are in one variable.

  • Standard form is ax^2 + bx + c = 0.
  • Every quadratic equation can be written in standard form.
  • The coefficients are a, b, and c.

  • A root is a value that makes the equation true.
  • Zeroes of a quadratic polynomial correspond to roots of the quadratic equation.
  • A quadratic equation has at most two roots.

Common Mistakes to Avoid

Any equation with x² is automatically a quadratic equation.

An equation is quadratic only if it is already written as ax^2 + bx + c = 0 in the exact order.

The leading coefficient in standard form must be positive, so only equations with a > 0 are acceptable.
